COMPASS CALIBRATION

6. COMPASS CALIBRATION
After the X4 Pro powers on, the blue LED of the X4 Pro will blink in a rotating pattern. Put the
X4 Pro on a level surface and do not move it. The transmitter display will show "Check
Compass", indicating that the X4 Pro is checking the compass. Keep the X4 Pro on a level
surface and slowly rotate it until the "Check Compass" disappears.
If the X4 Pro senses abnormalities in the compass sensor, it will enter compass calibration
mode. The transmitter screen will show "CAL compass 1"--spin the X4 Pro horizontally until
the LCD screen switches to "CAL compass 2", then vertically spin the X4 Pro until "CAL
compass 2" disappears. The compass will now be properly calibrated.
You can also follow the below method to calibrate the compass using GPS switch.
Do not calibrate the compass in areas of a strong magnetic field.
Do not have keys, magnets, or mobile phones on you while calibrating the compass.
Avoid large masses of metal while calibrating the compass.
